Selecting a Gallery Image

$

Hi everyone,

I'm trying to build an app which contains a page where the user can select an image from the gallery on their phone.

The approach I've taken is to create a DependencyService for image selection (following the dependency service guide)

Interface in the shared code:

public interface IGalleryImageService
{
    Uri SelectImage();
}

Android implementation (trying to follow the select a gallery image recipe):

[assembly: Dependency(typeof(GalleryImageService_Android))]
namespace DropZone.Droid
{
    public class GalleryImageService_Android : Java.Lang.Object, IGalleryImageService
    {
        public Uri SelectImage()
        {
            Context androidContext = Forms.Context;

            Intent imageIntent = new Intent();
            imageIntent.SetType("image/*");
            imageIntent.SetAction(Intent.ActionGetContent);

            androidContext.StartActivity(Intent.CreateChooser(imageIntent, "Select photo"));

            // How do I retrieve the image the user selects?
        }
    }
}

This successfully opens the gallery application on my Android phone but I do not know how to retrieve the image that the user selected. The select a gallery image recipe said to call StartActivityForResult which is not available Forms.Context (the closest I found was StartActivity).

How can I retrieve the result of the user selection in the gallery? Am I taking the right approach? I'm completely new to Xamarin so any input/guidance would really be appreciated! :)
